I must admit, I'm still not totally sure how to read these new H-serial numbers but it seems to me a code of aircraft, operational use, unit, sub-unit and individual bort number within that unit. (maybe
@Michael can explain better?)
As such the best understood part of the system is the 1st digit aka 1 = fighter and the final two digits aka 93 = bort number!
The construction number or which aircraft it is within a certain production batch can only be identified by the construction number, which is here not visible.
The most unconfirmed part of the new number is the 2nd to 5th digits.
